What is Network Security – Fundamentals of Network Security and Its Applications

What is Network Security

As more and more of our daily lives (both personal and professional) move online, we have to guard ourselves against cyberattacks. Cyberattacks have always been a threat for businesses and enterprises, as well as individuals, and attackers are always on the lookout to find and exploit vulnerabilities.

As technology evolves rapidly, old solutions have to make way for new ones. But how can you be sure that the new technologies that you implement aren’t adding vulnerabilities to your network? Before exploring the new and innovative solutions out there, it’s important to focus on your network security. Let’s examine what network security is and how it can help your business in preventing data loss and streamlining information flow.

What is Network Security?

In the simplest of terms, network security means using hardware and software tools to protect both your network and data. It covers accessibility, confidentiality, and data integrity used in hardware and software technologies.

Network security is quite a broad term, which includes numerous technologies, processes, and devices within its scope to protect against cyber threats. Attackers are always looking for vulnerabilities that can exist in a number of places, including your apps, devices, data silos, databases, locations, and even users.

Now that we have answered the question “what do you mean by network security?”, let’s explore its fundamentals, importance, and applications.

How Does Network Security Work?

Organisational networks are structured in layers. This makes it easier to put standards in place and implement security solutions. Any layer in the network security model is susceptible to cyberattacks, and it is imperative that your policies, software, and hardware are designed to combat every type of threat.

To understand exactly how network security works, it is important to understand the types of network security and how each type works in protecting these layers:

  1. Physical Network Security
    These security controls are specifically designed to prevent unauthorised people from accessing physical network components like cabling cupboards, routers, and so on. Physical network security focuses on controlling access using tools such as biometric authentication, like fingerprint scanning, and ID scanning locks.

  2. Administrative Network Security
    The administrative layer is all about protecting and controlling the security policies and user behaviours, including user authentication. It determines which areas users can access, and also guides the IT staff in implementing changes to the network infrastructure.

  3. Technical Network Security

    The technical network security layer protects not only the data stored on the network but also data that is in transit, within, across, or out of the network. Technical network security has a twofold protection process— it protects the data from being accessed by unauthorised personnel, and also protects it against any malicious or suspicious activities from the employees.

Importance of Network Security

Now that you have learned what network security is, it’s time to delve into its importance. As cyber threats grow every day, attackers are constantly looking for gaps in business security measures to exploit them.
